edit: Sources say the player is Jovan Belcher. Police have yet to confirm.

An unnamed Kansas City Chiefs player has committed suicide at the team facility and authorities are on the scene, the police confirmed to ESPN on Saturday morning.

Local reports say police are operating with the belief the player fatally shot his girlfriend at a house before driving to Arrowhead Stadium and killing himself at around 8 a.m local time. The Associated Press reported the player's age to be 25.

"We can confirm that there was an incident at Arrowhead earlier this morning," the Chiefs said in a statement. "We are cooperating with authorities in their investigation."

There were no other injuries at the team facility, police said.

The Chiefs (1-10) were preparing to host the Carolina Panthers on Sunday.

The NFL has told the Panthers to travel as planned to Kansas City on Saturday, the Charlotte Observer has reported, citing interim general manager Brandon Beane.

The Long Island mother of Kansas City Chiefs football player Jovan Belcher told investigators her son argued with his girlfriend Kasandra Perkins over their baby’s paternity before he shot her dead and killed himself, The Post has learned. Cheryl Shepherd — who was in her son’s suburban Missouri home the morning he shot Perkins nine times — told investigators after the shootings that there were questions about whether the West Babylon, LI-raised linebacker was the father of the couple’s 3-month-old daughter, Zoey, said sources familiar with the situation.

“The mother believed that there was an issue over whether [Belcher] was the father,” said a source close to the Chiefs with knowledge of the situation.

“She said he [believed he] wasn’t necessarily the father of the child.”

A Kansas City law-enforcement source confirmed, “She told [police] there was a question about the paternity.”

It’s unclear if the paternity issue was the reason for the final, violent end of the troubled relationship between Belcher, 25, and Perkins, 22.

“But the implication was that [paternity] was what the two of them were fighting about — that the baby might not have been his,” a source said.

Belcher fatally shot Perkins at 7:50 a.m. Dec. 1 after a heated argument that started at 7 a.m.

Shepherd, who had been visiting the couple, called 911 after her son fled the bloody scene.

Before bolting, Belcher apologized and kissed the dying Perkins and their baby daughter good-bye, according to the Kansas City Star.

He then drove to his team’s practice facility and shot himself in the head in front of the team’s coach and the general manager.

Asked by a reporter this week to elaborate on details of the fight and the paternity comments made to police, a woman who answered Shepherd’s cellphone said, “There will be no comment.”

The woman, who declined to identify herself, said Shepherd “doesn’t have anything to say about that.”

The Chiefs had been providing Belcher and Perkins with counseling for relationship and financial issues, police have said.

Under the surviving-child benefit of the NFL’s collective-bargaining agreement, little Zoey stands to receive more than $1 million.

NFL players-union spokesman George Atallah did not respond to several calls or e-mails asking whether the payout plan was contingent on a paternity test.

The child is slated to get $108,000 annually over the next four years, $48,000 in the fifth year and then $52,000 each year until she’s 18 — or 23, if she attends college.

Belcher’s beneficiary also will get $600,000 in life insurance, a $100,000 retirement account and $200,000 for each season he played. Belcher was in his fourth season with the Chiefs.

A Kansas City police spokeswoman said the baby’s paternity wouldn’t be part of the department’s murder-suicide probe.

“That would not be something they’re going to investigate,” said Sgt. Marisa Barnes. “It’s a ‘he-said, she-said’ so there’s no way to investigate. It would be nothing more than a civil matter.“

Police are expected to wrap up their investigation and present it to prosecutors as early as this week, Barnes said.

The night before the fatal argument, Perkins had been to a concert with friends. Belcher went out for dinner and drinks with another girlfriend, and cops found him passed out in his Bentley outside her apartment complex at 3 a.m. Belcher went back into the building to spend the night after cops woke him up.

Belcher and Perkins started dating in 2010 after being introduced by her cousin, Whitney Charles, who is married to Chiefs running back Jamaal Charles.

Zoey was born in September, and Facebook photos show a beaming Perkins and Belcher showing off their bundle of joy.

But the couple’s relationship was rocky. Perkins returned to her native Texas around Halloween, and later briefly moved in with Whitney and Jamaal Charles, friends said.

By Thanksgiving, Perkins was back with Belcher in their modest, three-bedroom home.

Belcher’s mom has temporary custody of the baby, but a permanent guardian has not been named.

Perkins’ family — who brought Zoey to a Texas memorial for her slain young mom last week — indicated that they will be involved in her upbringing.

“We will raise Baby Zoey in the knowledge of the love from which she was born,” Perkins’ family said in a statement.

The “loyal, honest and trusting” Perkins, they said, “was dedicated to starting her new family and beyond excited about being a mother to her sweet baby.”

There was no mention of Belcher at the service.

Family members declined to comment on the paternity issue.

“There has been a disheartening amount of rumors and speculation surrounding the tragic loss of our Kasi,” the family statement said.

“No one will every truly know why this happened, nor is there anything to be said that could justify or ease our pain.”

As much as the NFL and Kasi's family may not want to know the truth here, they need to find out of Belcher was the father or not. Is her being raised a millionaire by a family of the man who killed her mother and who is of no relation to her worth the money? Would you and your family stand for this or would you want her back even if it meant it could cost her potential benefits.

What a mess. What I want to know is are all of these benefits new to the collective bargaining agreement or did they also cover Derrick Thomas' kids in the same manner?

It's a double-edged sword. If he's not the father, his family has virtually no rights and Kasi's family then has complete say over how she is raised.

However, if they go out of their way to prove he's not the father, I'm sure the NFL will go out of their way to make sure she never receives a dime of the benefits they've said she'll get because she never was the daughter of an NFL player.

If Kasi was wanting Belcher's money, why would she openly confront him with the possibility that the child wasn't his and she was therefore not entitled to any of his money?

The way the laws are set up its to protect (and care for) the child:

If belcher wasnt the father by paternity, but raised the child as his, than he will still pay child support. Even if his name isnt on the birth certificate. This can be the case even without a formal marriage or common law marriage. If a court deems that a man has taken on the fatherly responsibilities for a child than he is on the hook b/c it is in the best interest of the child.

There have been plenty of instances where men have to pay spousal support even in cases of infidelity before and during the marriage if he is the primary bread-winner.

If he is not the father I don't see how she's legally entitled to his benefits. The couple WAS NOT MARRIED. The NFL can give some sort of payoff to help the kid and make a good gesture but I do not see how Belcher's family is entitled to a dime if he is not the father.

Not to mention, they should not be allowed to have custody of the child PERIOD.
